Support the Lab, at lightning speed.
All our apps — StreamVision, Sun Day, SmartCaddie — are free and ad-free. If they are useful to you and you'd like to help, you can send a Bitcoin donation over the Lightning Network: instant, permissionless, from just a few satoshis.
Our Lightning address works like an email address: type it into any compatible wallet, or scan the QR code.
As per our statutes (Art. 8), every donation is fully reinvested in the development of our free applications.

Why the Lightning Network?
The Lightning Network is a payment network built on top of Bitcoin. Where a regular on-chain Bitcoin transaction can take several minutes and cost a few euros in fees, a Lightning payment is:
- Instant — the donation arrives within seconds;
- Nearly free — fees amount to fractions of a cent;
- Accessible — you can send from just a few satoshis (1 satoshi = 0.00000001 BTC);
- Direct — no banking intermediary, no account to create, no personal data requested.
It is the ideal way to donate any amount you like, even a symbolic one — the equivalent of a coffee already covers part of our infrastructure costs.

Which Lightning wallet should I choose?
There are many free wallets. Three solid options to get started, available on iOS and Android:
Wallet of Satoshi
Instant onboarding, ideal for a first donation. Custodial wallet: perfect for small amounts.
Phoenix
Built by ACINQ (France). You keep control of your funds — recommended if you already use Bitcoin.
Blink
Simple and fast, with a Lightning address included. It is the service hosting our own receiving address.
You can also send from most exchanges that support Lightning withdrawals.
What is a Lightning address?
A Lightning address is a human-readable identifier in email format — like dihlabs@blink.sv — that lets you receive Lightning payments without generating an invoice each time. Your wallet automatically converts it into a payment request (LNURL-pay). It is today's simplest standard for Bitcoin donations and tips.
